 Summer is tougher and hotter when you are carrying around a bunch of extra weight. Trust me, I know. I'm Pete Callener, and I had an extra 90 pounds of insulation before I joined Ph.D. Weight Loss and Nutrition. You can't hide that kind of weight, but Ph.D. is a proven process that works. I am that proof. I immediately felt better, and I started looking better. The Ph.D. program teaches you what to eat and when.
